- srncrrrcn'rronronningm of Letters 2 To all whom it may concern.- Be itknown that I, HENRI CHARLIER, was zen of the Republic of France,residing-at I Philadelphia, in the county of, Philadelphia andState-ofBennsy ania,have invented certain new and useful mprovementsinSmelting-Furnaces, which the followingis a speci'- vfication, referencebeing; had therein to the accompanyingdrawin'ga- My'invention-mlatestosmelting-furnaces. Tend has -particu.la'r--r eference to that class offurnaces in whichthe crucible containing the melted metal j'isnotremoved from the the. when pouring out. the metal or recharging thecrucible-.- I p -.'.The;objects"of"'my invention are, first, to. soconstruct.the' furnace that when any-part ofthe brick-lining'ofthefire-chamber needs renewing, the worn-out portion can be taken so outand replaced'by' a new one without in any manner disturbing those partsof the brick lining that do not need renewing, and, second, toprovidemeans whereby a broken or worn out crucible may be easily and quicklyre- 2 without disarranging the other-parts of the furnace or allowing itto cool oif.

Toaccomplish the desired results, ,1 conuectthe lower part of thefire-chamber, in which the grate-bars are supported, and also the upperpartor cover of said firechamber, to'the main body of the furnace by ahinge that will allow these" top and bottom; portions of the furnace tobe turned back out'efthe' way when desiring to remove a worn-outcrucible or to renew any part ofthe brick lining of the fire-chamber.

In the accompanying drawings, Figure 1 is a vertical sectional viewthrough the middle ofaifurnace having my improvement therein.

Fig. -2 is a plan view of the furnace andlifting mechanism.
